• Easy to Install – No tools required. Simply insert the foam blocks into the side panel gaps or between the window sash and AC frame. The foam compresses to create a tight seal.
• Durable and Reusable – Made from high‑density, weather‑resistant foam that holds its shape without crumbling. Can be reused season after season. The customizable design makes this product suitable for most standard window AC units.
